If the expression is 2*x*3, x must be 1/3 in order to cancel out the 3 which would leave the 2.
The square footage of the room is length times width...in this case 16 x 12 =192 then divide that by 7 and it can accommodate 27 people.

Answer:
112x m^2
Step-by-step explanation:
The area of a trapezoid is given by
A = 1/2 ( b1+ b2) h
where b1 and b2 are the bases
A = 1/2 ( 11x+17x) * 8
= 1/2 ( 28x)8
= 112x m^2
Answer:400
Step-by-step explanation:
3 hours: 400 times 2=800
6 hours: 800 times 2=1600
9 hours: 1600 times 2=3200
12 hours: 3200 times 2=6400
15 hours: 6400 times 2= 12800
18 hours: 12800 times 2=25,600
21 hours: 25,600 times 2= 51200
24 hours: 102,400
